EU Medical Device Classification

What is EU Medical Device Classification?

According to MDR 2017/745, Article 51 of the EU Medical Device Classification categorizes medical devices into classes I, IIa, IIb, and III, considering their intended purposes and their inherent risks. The risk is incremental from class I to class III. The Medical Device Directive (MDD) and Medical Device Regulation (MDR) both use a rule-based classification pattern for medical devices. In the new MDR, there are now 22 rules in Annex VIII.

The determination of the medical device classification and the corresponding classification rule is the first step in the EU CE marking process. Based on the class and the rule of the device, the technical file and the Notified Body application can be filed.
